[0017] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0018] like Figures 1 to 5 As shown, an embodiment of this utility model provides a hydraulic fixture for machining disc brake cylinders, including a support frame 1, a positioning table 2, a gripper 3, and a clamping adjustment component 4.

[0019] Specifically, the positioning platform 2 is fixedly installed on the support frame 1, and the positioning platform 2 is provided with a plurality of movable sliding grooves 5, and the movable sliding grooves 5 are matched with the gripper 3.

[0020] The clamping claws 3 are provided in multiple ways, and the multiple clamping claws 3 are movably disposed in the movable slide groove 5. The clamping claws 3 are used to clamp and fix the disc brake cylinder body to be processed.

[0021] The clamping adjustment member 4 is disposed below the positioning platform 2, and the clamping adjustment member 4 is connected to the gripper 3 in a transmission manner. The clamping adjustment member 4 is used to synchronously drive multiple grippers 3 to close or separate.

[0022] In this embodiment, when a workpiece (such as a disc brake cylinder) needs to be clamped and processed, firstly, the workpiece is placed in the middle of multiple grippers 3, waiting for the grippers 3 to clamp and fix the workpiece. Then, the clamping adjustment component 4 drives the grippers 3 to close synchronously, and the grippers 3 can clamp and fix the edge of the workpiece during the closing process. When the grippers 3 are in close contact with the outer edge of the workpiece, the clamping and fixing operation of the workpiece is realized. Finally, after the workpiece is clamped and fixed, the processing operation can be performed on the workpiece.

[0023] Compared with existing technologies, this solution utilizes the clamping adjustment component 4 to drive multiple grippers 3 to close or separate synchronously, which can quickly complete the clamping and releasing of the disc brake cylinder body. It not only has a simple mechanical structure, but also greatly improves the processing efficiency of the disc brake cylinder body, and has the characteristics of simple structure and convenient operation.

[0024] Furthermore, the movable slide 5 is evenly distributed around the positioning platform 2, and the movable slide 5 is arranged radially, with the cross-section of the movable slide 5 having an inverted "convex" shape.

[0025] Specifically, a plurality of mounting grooves 6 are provided along the length of the platform on the bottom surface of the movable slide 5, and movable ball bearings 7 are movably disposed in the mounting grooves 6.

[0026] In this embodiment, the gripper 3 is slidably disposed within the movable groove 5, and the gripper 3 is arranged radially. During the synchronous closing process of the gripper 3, the circular workpiece to be processed can be synchronously clamped and fixed, so that the workpiece to be processed is stably kept in the center position and will not shift. When the gripper 3 synchronously separates, the gripper 3 releases the clamping operation on the workpiece to be processed, making it easy to remove the workpiece.

[0027] The top surface of the movable ball 7 is higher than the platform of the inner bottom surface of the movable slide 5 and is used to slide and support the gripper 3. During the movement of the gripper 3, the frictional resistance between the gripper 3 and the inner bottom platform of the movable slide 5 is reduced, making the movement of the gripper 3 smoother.

[0028] Furthermore, the gripper 3 includes a movable slider 8, an arc-shaped positioning sleeve 9, and a drive column 10.

[0029] Specifically, the movable slider 8 is slidably disposed within the movable groove 5, and the movable slider 8 is in contact with and slides against the upper surface of the positioning platform 2.

[0030] The arc-shaped positioning sleeve 9 is fitted onto the movable slider 8, and the arc-shaped positioning sleeve 9 has an arc-shaped positioning cavity 11.

[0031] The drive column 10 is mounted on the movable slider 8, and the drive column 10 passes through the movable slide groove 5 and extends to the bottom of the positioning platform 2.

[0032] In this embodiment, the arc-shaped positioning sleeve 9 is a detachable structure. During the selection process of the arc-shaped positioning sleeve 9, an arc-shaped positioning sleeve 9 with a suitable arc-shaped positioning cavity 11 can be selected according to the outer diameter of the workpiece to be processed. After the selection of the arc-shaped positioning sleeve 9 is completed, the arc-shaped positioning sleeve 9 can be fitted onto the movable slider 8, which can match workpieces with different outer diameters.

[0033] In one specific embodiment, an anti-slip pad 12 is fixedly installed on the inner wall of the arc-shaped positioning cavity 11, and the anti-slip pad 12 is fitted against the inner wall of the arc-shaped positioning cavity 11. The anti-slip pad 12 can reduce the friction between the inner wall of the arc-shaped positioning cavity 11 and the workpiece to be processed, thereby enabling the workpiece to be processed to be securely clamped and fixed.

[0034] Furthermore, the clamping adjustment component 4 includes a drive disc 13, a transmission column 14, a transmission connecting rod 15, and a rotary hydraulic cylinder 16.

[0035] Specifically, the drive disk 13 is rotatably mounted on the bottom surface of the positioning platform 2.

[0036] The transmission column 14 is disposed on the bottom surface of the drive disk 13, and the transmission column 14 is offset from the center of the drive disk 13.

[0037] The transmission link 15 is movably disposed between the transmission column 14 and the drive column 10, and the transmission link 15 is connected to both the transmission column 14 and the drive column 10 in a transmission manner.

[0038] The rotary hydraulic cylinder 16 is fixedly mounted on the support frame 1, and the rotary hydraulic cylinder 16 is connected to the drive disc 13 in a transmission manner.

[0039] In this embodiment, when it is necessary to clamp and fix the workpiece to be processed, the rotary hydraulic cylinder 16 drives the drive disk 13 to rotate. During the rotation of the drive disk 13, the drive disk 13 drives the transmission column 14 and the moving slider 8 to move synchronously towards the center position through the transmission connecting rod 15, thereby achieving the clamping and fixing of the workpiece to be processed. When it is necessary to release the clamping and fixing of the workpiece to be processed, the rotary hydraulic cylinder 16 drives the drive disk 13 to rotate in the opposite direction, thereby achieving the synchronous separation of the grippers 3.

[0040] In one specific embodiment, the transmission connecting rod 15 has transmission holes 17 at both ends that match the transmission column 14 and the drive column 10, and the ends of the transmission column 14 and the drive column 10 are detachably provided with positioning pins 18. When installing the transmission connecting rod 15, the transmission holes 17 at both ends of the transmission connecting rod 15 are fitted onto the transmission column 14 and the drive column 10, and the positioning pins 18 are used for positioning to facilitate installation.

[0041] Unlike existing technologies, this utility model has at least the following beneficial effects: This utility model utilizes a clamping adjustment component to drive multiple jaws to simultaneously close or separate, enabling rapid clamping and release of disc brake cylinder bodies. It not only has a simple mechanical structure but also greatly improves the processing efficiency of disc brake cylinder bodies, featuring simple structure and convenient operation.

[0042] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
